Mrs. Peters needed to raise money to bring her class to the Air and Space Museum in Washington, D.C. With only a few weeks left before the deadline, the class was raising an average of $45 every day from online donations. Mrs. Peters was worried they might not raise the last $1,000 in time. That evening, she posted a story about the class trip on an education website, and the donation rate doubled overnight! The new rate stayed the same for the remaining 3 weeks until the deadline, and they raised more than their goal! How much extra did the class raise?
Please Could You Help???
2*45 * 3*7 = 1890
Ty so much again ty
Yes, I can help you with that!
To determine how much extra money the class raised, we first need to calculate the total amount they raised before the donation rate doubled.
Since they were raising an average of $45 every day, we can multiply the average by the number of days in 3 weeks (21 days) to find the original amount raised.
$45/day * 21 days = $945
Therefore, the class originally raised $945 before the donation rate doubled.
Now, to find out how much they raised after the donation rate doubled, we can calculate the new average daily donation after the rate doubled.
Since the new rate doubled the old rate, the new average donation will be $45 multiplied by 2, which equals $90 per day.
The new daily average of $90 per day remained for the remaining 3 weeks.
So, the total amount raised after the donation rate doubled can be calculated by multiplying the new daily average by the number of days in 3 weeks.
$90/day * 21 days = $1890
Since they originally raised $945 and then raised an additional $1890, the extra amount they raised can be found by subtracting the original amount from the new amount:
$1890 - $945 = $945
Therefore, the class raised an extra $945 in donations after the donation rate doubled.
